add support for new URL() (#28940)
Currently `new URL()` for server assets is completely broken because of the `publicPath` that is used for them too. `new URL()` for SSR is broken on windows as it's using absolute urls on the windows filesystem. And `new URL()` is using an incorrect filename

* Place all `asset`s correctly in `/_next/static/media` with `[name].[hash:8][ext]`
* Added a separate runtime chunk for api entries, without `publicPath`
* Introduce separate layer for api entries, which uses server-side URLs.
* Otherwise new URL() will return a faked relative URL, that is identical in SSR and CSR
* Disables react-refresh for api entries

Fixes #27413
